California’s major dams face risks of floods and failure due to climate change

Major dams in California are five times more likely to flood this century than the last one due to global warming, a new study finds, possibly leading to overtopping and catastrophic failures that threaten costly repairs and evacuations. That means Californians can expect more disasters like the Oroville Dam, whose overflow channel failed in 2017 after days of flooding had filled state reservoirs to 85% of their capacity.
